I like the games on Premier's channel better, but I like the commentary on TonyG's better.
I do think it's mostly a personality thing though. Like Premier is very analytical, so he's interested in telling you what's happening through the lens of whether or not he thinks it's smart. TonyG is also smart about the game, but he talks more about why he thinks the player is doing what they're doing and doesn't put his own perspective on it too much.
I prefer how much TonyG clicks around to give the viewer insight as to what's happening without even having to talk about it. It's way more engaging that way.
Also Premier is never gonna call "Joe-say" a shithead lol, but it got a solid LOL out of me. Best part is that it wasn't even a subjective statement. Called him out for the no gg too. Nice haha.
